SPEGIFIGA'I'ION forming part of' Letters Patent N0. 444,910, dated J'anuary 20, 1891.

T0 all w7wm z't may conoern:

Be it known ih-at I, WILLIAM G. SEARS, a eitizen of the United States, residing ab Chattanooga, in the conntyof Hamilton ancl State of Tennessee, have invented certain new and useful Improvements in Rail-Ties; and I clo hereby declare the following to bea full, elear, and exaci: description 0f the invention, such as will enable others skillecl in the art to which itappertains to make anti nse the san1e.

This invention relates to an improvernent in oross-ties for railways, the objeot being to provide a more perfeet metallic cross-tie 01 sleeper Wl1ioh may afiord ayielcling elastic 01 enshioned seat for the rail, thns obviating the oonstant pouncling ineident to the use 0i' the ordinary railway constrnction, and especially charaoteristie of inelastic ties of solid iron o1 steel,which results speeclily in tl1e injnry ancl destruotion of the rails and ties; anal the invention consists, essentially, in the eombination, constrnetion,ancl arrangement of parts, substantiallyas will be hereinafter clesoribed and claimecl.

In the annexed drawings, illustrating my inve'ntion, Figure l is a perspective view of my improved rail-tie. Fig. 2 is a side elevation of a railway-rail snpported npon my improved tie to whioh it is seenrecl, the tie being shown in transverse seetion on the linex a: of Fig. Fig. 3 is an enlargecl cletail plan view showing one 015 the transverse rail-sup porting spring-plates ancl the rail seenred thereon by a track-fast-ener. Fig.4: is an enlarged partial perspeetive view 0f my im pioved metallic tie, showing eertain details of its constrnction.

Similar letters 0f reference designate 001- responding parts thronghout all. the difierent figures of the drawings My improvecl hollow metallic rail-tie is made in the form of a hollow trongh, gutter, box, 01 receptacle, of steel or other metal 0f snitable strength and thickness ancl having a proper length so adapt it forbeing plaeed in the ballast of the road-bed, lilze the ordinary tie, A denoting its bottom, and A A its sides, which are preferably inelinecl outwardly, the upper edges of these sicles A A being provided with horizontal fianges a a, Whieh are notched 01 indentecl ab a a near each encl, where the transverse rail-snpporting plates Applicut-ion file(l April 16, 1890. Serial N0. 348,147. (N0 model.)

are to'be seonred npon the tie-box. In Fig. 2 tl1e hollow trough is Seen embedded in the ballast of the roacl-becl, which is firmly pressed aronncl it in such a manner thab tl1e flanges a a a1e on a level Witl1 the surfaee of the bed o1 ab a trifling distance above it.

Seenrecl npon the open nie 01 sleeper loox, ne-ar each end thereof, ab points where Ehe 'rails oross tl1e tie, and ser.ving to support the latter, a1e flat elastic plates B B, preferably macle of spring-steel and having a convenient ancl snitable thickness ancl Width. These plates a1e preferably arehed, eurvecl, 01 ronncled, so as to be somewhat higher ab the midclle than at tl1e ends. They are seeured to the tie in some sniable manner. A preferable way of secnring them is to provide the1n at the ends with bencls or inturned flanges b, whieh forn1 grooves to receive tl1e flanges a 011 tl1e nie, ancl also with a oonvenient number of projections b struek up fromsaicl flanges (see Fig. 2) an l adapted 110 enter tl1e notehes a a in the horizontal tie-fiangesa a. Otl1er xnocles of Conneeting the spring-plates may cloubtless be clevised and snbstitutecl fo1 that here clescribed with good efceet.

O denotes a seouion of a rail that rests npon n1y improved tie, it being shown for the purpose 0f rn0re clearly explaining ohe invention. This rail is seeurecl upon tl1e supporting-plate by some strong traek-fastening, such as thav describecl in my pencling application for patent, filed March 15, 1890, Serial N0. 34:3983, and oonsisting, essentially, of' a fixed clamp c, aeting on the inner fiange of the 1ail, an onter bar d, having a doubly-inelined face, a bracebloek having an inclinecl face ancl Wih one sicle pressing against the objeet, and an inierposed wedge f between the outerbar and the brace, said wedge having is wedgingfaces eacl1 doubly inelined, and the inner elamp, onter bar, ancl braced3loek being fixed in slots in tl1e rail-snpporting plate B, as shown.

' Having thns described my invention, what I clain1 as new, anti desire to secure by Letters Patent, is'

l. The combination of the hollow tie-box having its sicles provicled witl1 horizontal flanges, the transverse spring rail-snpporting plat-es having projections ab alle ends adapted so enter notches in the horizontal flanges ancl supporting spring-plates having the bends ab eaoh end, and oho struck-up projeotions adapted t0 enter the notches in tho horizontal fianges, substantially as described.

In testimony whereof I affix my signature in presenee of two witnesses.

WILLIAM G. SEARS.
